Explanation:
Detailed explanation-1: -Answer: C. Median, because there is an outlier. The outlier could be incorrect and would influence the mean too much.
Detailed explanation-2: -The median is usually preferred to other measures of central tendency when your data set is skewed (i.e., forms a skewed distribution) or you are dealing with ordinal data. However, the mode can also be appropriate in these situations, but is not as commonly used as the median.
Detailed explanation-3: -The mean and median are usually used to measure the central tendency of a numerical data set. When the data set is skewed the median is the preferred measure of central tendency.
